Classification of kinematic pairs with examples
Kinematic pairs can be classified on basis of their nature of contact, constraints, and nature of relative motion between the elements in contact. Here is the detailed classification of kinematic pairs with the relevant example. We can easily understand kinematic pairs once we understand the concept of degree of freedom. Classification of kinematic pairs According to […]
What is degree of freedom in mechanics?
When a link is connected to one or more other links, it imposes a restriction on the relative motion of the combined link or mechanism. This number of restrictions may vary according to the type of link and connection they made with each other. Basically, there are 3 transitional and 3 rotational motions are considered. […]
Cam and follower mechanism types and functions
A cam is a mechanical member which impart desired motion to the follower by direct contact. Cam may be rotating or reciprocating while a follower may be rotating, reciprocating and oscillating. A cam-follower forms higher pair as they have point contact at the junction. From now we will term cam and follower mechanism as cam […]

Types of constrains in mechanism or machines
Constrain means restriction. In mechanics, we got many redundant motions which need to restricted to save energy and work. We need to focus only on desired motion to get output from that mechanism. Sometimes these constrains are needed to be applied externally to restrict these additional redundant motions. Types of constrains in mechanism or machines […]
